As helium is added to a balloon, the balloon always keeps a spherical shape. If helium is added at the rate of 120x cubic inches per minute, how fast is the radius growing at the
moment when radius is 10 inches.

Acircle has a diameter will endpoints of (-2,8) and (6, 4). what is the center of the circle

The radius of the circle is 4 cm and the measure of the central angle is 90° the area of the sector with a central angle measuring 90° and radius of length 4 cm is vt cm the triangle in the sector is 4 cm the area of the triangle is v/cm² the area of the segment of the circle is (471 - ) cm?

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b
